Yahoo to add Do Not Track option to its global web empire

Yahoo Inc. says it will add a “Do Not Track” option to the headers of its web properties around the world so consumers can decide how they want to be seen by Yahoo advertisers. The digital media company says the option will roll out this summer.

Do Not Track describes a proposed federal policy designed to protect the online privacy of consumers by allowing them to opt-out of data collection efforts by online marketers; those marketers often use web data to target advertisements at consumers based on their browsing histories.
